摘　　要：400 kA铝电解槽焦粒焙烧启动电耗高、装槽物料多且价格昂贵,导致整个焙烧启动期间成本偏高,采取缩短焙烧时间、减少冰晶石用量、降低启动电压等措施,每台电解槽可降低焙烧启动成本约4万元,减少氟化氢等温室气体排放量约24%。At present the coke particles roasting startup of 400kA aluminum reduction cell has high power consumption,many Slotting materials for reduction cell and high-priced,so that the cost for whole roasting startup period was high,so we adopted the measures like shorten the roasting time,reduce the cryolite dosage,reduce the startup voltage and so on,therefore the cost of roasting startup for each aluminum reduction cell can be saved about￥40000 RMB,the emission of hydrogen fluoride and the other greenhouse gas can be reduced about 24%.
